The CAS Registry Mumber 91073-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,7 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91073-91:
(7*9)+(6*1)+(5*0)+(4*7)+(3*3)+(2*9)+(1*1)=125
125 % 10 = 5
So 91073-91-5 is a valid CAS Registry Number.
